We all know that I6 has the best steering rack with pinion
Based on my experience and research on US/ EURO forums to be able to take the best of them
they need to be rebuild every ~100k
I don't want to argue if it is necessary or not , if you think your steering rack
is perfect after 100k+ miles this thread is not for you
So lets start
1. All I6 has the same steering rack
The ZF # is 7852 955 304 and it is the same for 528i, 525i and 530i
( remember this number 7852 )
I personally checked 3 steering racks for M54 and they all have the same ZF number
The BMW # for steering rack w/o Servotronic ( US version ) is 32136751745
2. For this steering rack 7852 this is what i found so far :
